Midwater trawling catches pelagic fish such as anchovies , and mackerel , whereas bottom trawling targets both bottom-living fish groundfish and semi-pelagic species such as cod , squid , shrimp , and rockfish.
Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively pair trawling. Global catch from bottom trawling has been estimated at over 30 million tonnes per year, an amount larger than any other fishing method.
An early reference to fishery conservation measures comes from a complaint about a form of trawling dating from the 14th century, during the reign of Edward III.
A petition was presented to Parliament in calling for the prohibition of a "subtlety contrived instrument called the wondyrchoum ".
The response from the Crown was to "let Commission be made by qualified persons to inquire and certify on the truth of this allegation, and thereon let right be done in the Court of Chancery ".
Thus, already back in the Middle Ages, basic arguments about three of the most sensitive current issues surrounding trawling - the effect of trawling on the wider environment, the use of small mesh size, and of industrial fishing for animal feed - were already being raised.
Until the late 18th century sailing vessels were only capable of towing small trawls. However, in the closing years of that century a type of vessel emerged that was capable of towing a large trawl, in deeper waters.
The development of this type of craft, the sailing trawler, is credited to the fishermen of Brixham in Devon. The new method proved to be far more efficient than traditional long-lining.
At first its use was confined to the western half of the English Channel, but as the Brixham men extended their range to the North Sea and Irish Sea it became the norm there too.
By the end of the 19th century there were more than 3, sailing trawlers in commission in UK waters and the practice had spread to neighbouring European countries.
Despite the availability of steam, trawling under sail continued to be economically efficient, and sailing trawlers continued to be built until the middle of the s.
English commissions in the 19th century determined that there should be no limitation on trawling. They believed that bottom trawling, like tilling of land, actually increased production.
As evidence, they noted that a second trawler would often follow a first trawler, and that the second trawler would often harvest even more fish than the first.
The reason for this peculiarity is that the destruction caused by the first trawl resulted in many dead and dying organisms, which temporarily attracted a large number of additional species to feed on this moribund mass.
Bottom trawling has been widely implicated in the population collapse of a variety of fish species, locally and worldwide, including orange roughy , barndoor skate , shark , and many others.
The design requirements of a bottom trawl are relatively simple, a mechanism for keeping the mouth of the net open in horizontal and vertical dimensions, a "body" of net which guides fish inwards, and a "cod-end" of a suitable mesh size, where the fish are collected.
The size and design of net used is determined by the species being targeted, the engine power and design of the fishing vessel and locally enforced regulations.
The simplest method of bottom trawling, the mouth of the net is held open by a solid metal beam, attached to two "shoes", which are solid metal plates, welded to the ends of the beam, which slide over and disturb the seabed.
This method is mainly used on smaller vessels, fishing for flatfish or prawns , relatively close inshore. Otter trawling derives its name from the large rectangular otter boards which are used to keep the mouth of the trawl net open.
Otter boards are made of timber or steel and are positioned in such a way that the hydrodynamic forces, acting on them when the net is towed along the seabed, push them outwards and prevent the mouth of the net from closing.
These bobbins vary in their design depending on the roughness of the sea bed which is being fished, varying from small rubber discs for very smooth, sandy ground, to large metal balls, up to 0.
These bobbins can also be designed to lift the net off the seabed when they hit an obstacle. These are known as "rock-hopper" gear.
The body of the trawl is funnel-like, wide at its "mouth" and narrowing towards the cod end, and usually is fitted with wings of netting at the both sides of the mouth.
It is long enough to assure adequate flow of water and prevent fish from escaping the net, after having been caught. It is made of diamond-meshed netting, the size of the meshes decreasing from the front of the net towards the codend.
Into the body, fish and turtle escape devices can be fitted. These can be simple structures like "square mesh panels", which are easier for smaller fish to pass through, or more complicated devices, such as bycatch grills.
The cod end is the trailing end of the net where fish are finally "caught". The size of mesh in the cod end is a determinant of the size of fish which the net catches.
Consequently, regulation of mesh size is a common way of managing mortality of juvenile fishes in trawl nets. The idea that fish are passively "scooped up" is commonly held, and has been since trawling was first developed, but has been revealed to be erroneous.
Since the development of scuba diving equipment and cheap video cameras it has been possible to directly observe the processes that occur when a trawl is towed along the seabed.
The trawl doors disturb the sea bed, create a cloud of muddy water which hides the oncoming trawl net and generates a noise which attracts fish.
The fish begin to swim in front of the net mouth. As the trawl continues along the seabed, fish begin to tire and slip backwards into the net.
Finally, the fish become exhausted and drop back, into the "cod end" and are caught. Bottom fishing has operated for over a century on heavily fished grounds such as the North Sea and Grand Banks.
While overfishing has long been recognised as causing major ecological changes to the fish community on the Grand Banks, concern has been raised more recently about the damage which benthic trawling inflicts upon seabed communities.
This species is home to a diverse community of deep sea organisms, but is easily damaged by fishing gear. On 17 November , the United Nations General Assembly urged nations to consider temporary bans on high seas bottom trawling.

Bottom Line to host benefit. Changes to energy markets are now transforming the real estate management field, with opportunities to generate savings and revenues that can boost the bottom line for building owners, while raising the book value and investment cache of the properties under management.
A few enlightened professionals recognized the need for a formal approach to investment recovery as a contributor to company bottom lines and formed an organization to foster knowledge and to identify and promote best practices in the field.
But will that justify the 1 to 2 percent off the bottom line for the investor? Will CEOs take it laying down--or push back? Want more boy attention? The suspended solid plumes can drift with the current for tens of kilometres from the source of the trawling, increasing sedimentation rates in deep environments .
These plumes introduce a turbidity which decreases light levels at the bottom and can affect kelp reproduction.
Phosphorus is often found in high concentration in soft shallow sediments. Even in areas where the bottom sediments are ancient, bottom trawling, by reintroducing the sediment into the water column, can create harmful algae blooms.
The UN Secretary General reported in that 95 percent of damage to seamount ecosystems worldwide is caused by deep sea bottom trawling. Today, some countries regulate bottom trawling within their jurisdictions: Beyond national jurisdictions, most bottom trawling is unregulated either because there is no Regional Fisheries Management Organization RFMO with competence to regulate, or else what RFMOs that do exist have not actually regulated.
The major exception to this is in the Antarctic region, where the Convention for the Conservation of Antarctic Marine Living Resources regime has instituted extensive bottom trawling restrictions.
This still leaves most of international waters completely without bottom trawl regulation. All countries fishing in the region accounting for about 25 percent of the global ocean agreed to exclude bottom trawling on high seas areas where vulnerable ecosystems are likely or known to occur until a specific impact assessment is undertaken and precautionary measures have been implemented.
Also observers will be required on all high seas bottom trawlers to ensure enforcement of the regulations. Palau President Tommy Remengesau has called for a ban on destructive and unregulated bottom trawling beyond national jurisdictions.
Palau has led the effort at the United Nations and in the Pacific to achieve a consensus by countries to take this action at an international level.
In , New Zealand Fisheries Minister Jim Anderton promised to support a global ban on bottom trawling if there was sufficient support to make that a practical option.
